+Subject: [PATCH] cmake: Exclude AARCH64-specific KleiDiAI kernels from armv7
+ builds
+
+The KleiDiAI matrix multiplication kernels use AARCH64-specific instructions
+that are incompatible with armv7 architecture.
+
+Update CMake and add expressions to conditionally exclude these files when
+ACL_ARCH_ISA is set to armv7, preventing build failures on 32-bit ARM platforms.
